IMPROVEMENT IN CALK ATTACHMENTS.

Specification forming part of Letters Patent No. 219,876, dated September :23, 1879; application led December 2, 1878.

To all whom it may concern Be it known that I, J oHN D. RosENBEnGER, of the city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in `Horseshoe-Oalks, of which the following is a speciication.

This invention is an improvement on my Patent No. 185,700.

The object of the invention is such a construct-ion of the calli-plates as will admit of being rinly and expeditiously attached to ordinary horseshoes or detached therefrom easily and quickly; and the nature of the invention consists of a pair of metallic plates which lit the under side ci' the shoe and bind against its inner edge and the upper side of the shoe along said edge, in combination with a pair of metallic straps which are pivoted to lugs on the under side of said plates at their lower end, and at their upper ends have slots," with which are connected a tightening-strap, which is drawn over'the upper part ot' the hoof and fastened, as hereinat'tervdescribed.

In the accompanying drawings, Figure l is a side elevation of a shoe and calli-plates and their attachments. Fig. 2 is a top view of the hoot' and the attaching devices of the calkplates O C. Fig. 3 is a bottom View, showing the connection of said plates with the shoe. Fig. 4 is a perspective view of one of the calkplates G. Fig. 5 is a cross-section of one of the calli-plates and the side of the shoe with which it is connected, at the broken lines x a? of Figs. l and 3. Fig. 6 is a like section of the same at the broken lines y y. Fig. 7 is a side View of a portion of the rear end oi' one of the calk-plates C, showing a modifica-tion in the connection of straps D. Fig. Sis an endelevation of the same.

Like letters of reference in all the figures indicate the same parts.

A represents the hoof of a horse; B, an ordinary shoe, and C C metallic plates having toe-calks a and heel-calks b'. These plates have against the inner edge of the shoe, which iangeA has an extended iiange, c', whereby a groove, d, is formed of suitable dimensions for ttin g the under side ofthe shoe, its inner edge, and around the upper corner, as seen clearly in Fig. 5.

D D are metallic straps, which have their lower ends bent inward and formed to iit the round holes c in the lugs f in the rear calks, b, of the plates C, and are provided with continingnuts y.

rEhe upper ends of the straps have slots h, with which is connected the exible strap E, which is made ot' leather or other suitable material. It drawn tightly over the front of the hoof .A and buckled, as seen in Fig. 2, whereby the straps D D are drawn forward and the plates C O thereby forced toward the front ot the shoeuntil their front ends meet each other, as seen in Fig. 3, and the plates brought iirlnly into connection with the shoe, the grooves d partly encircling the inner edge thereof, as seen in Fig. 5. The grooves are somewhat narrowed at their bottom, to insure a tight fit upon theshoe. p

Instead of having lugs fin the rear of the calks b they may be dispensed with by widening the calks, as shown in Figs. 7 and S, and providing them with holes ei'or the connection ofthe straps D. In this case the straps may have a screw connection with theholes and the nuts g be dispensed with.

If desired, a chain may be used instead of the flexible strap E.

I claim as my invention- 1. The calli-plates C C, having lugs f, provided with holes e. substantially in the manner and for the purpose set forth.

2. rEhe metallic straps D D, having their lower ends bent inward and their upper ends provided with slots h, in combination with the calli-plates C O and strap E, substantially in the manner and for the purpose set forth.
